Lord O'Neill of Clackmannan: My Lords, I am very grateful to the noble Lord for giving way and if he was going to touch on this point, I hope that he will forgive me, but, with his particular knowledge of the Severn Estuary and south-east Wales, what is his view on the potential of a Severn barrage? Does he take the view that I and, more importantly, a number of Members of Parliament representing Welsh constituencies, do that the endlessly renewable energies of the Severn Estuary are an asset of which we should take full advantage?
